  • the aqueous dispersion can be prepared by preparing a mixture containing the leaf tobacco extract or a concentrate thereof as a dispersion medium, a dispersion interference-preventing agent comprising an organic acid, and powder of the heat-irreversibly coagulating glucan, and stirring the mixture to disperse the powder of the glucan into the dispersion medium, thereby preparing a slurry having an increased viscosity.
  • the cigarette-like article can be prepared by mixing the tobacco flavor-generating material obtained in the stage (d) with a sheet tobacco material; forming this mixture into a sheet form; cutting or pulverizing the obtained sheet to prepare a tobacco flavor-generating medium in a form of cuts or powder; and, in the stage (f), combining the flavor-generating medium with the tobacco flavor-adjusting material.
  • a leaf tobacco is subjected to extraction process, so as to obtain a tobacco extract liquid and a leaf tobacco fibrous residue, the residue after the extraction, which does not substantially contain any tobacco extract.
  • a leaf tobacco for example, 20 to 200 parts by weight of a leaf tobacco can be added to 1000 parts by weight of water, and then this mixture is stirred while being heated at, for example, 10 to 90°C, so as to extract a leaf tobacco extract.

  • the viscosity of the slurry is not increased sufficiently, resulting in flowing-out of the slurry, casting-failure or scattering of the slurry in the stage of forming a sheet, and further resulting in reduction in gel strength in a subsequent thermal gelation step, causing the inhibition of the gel formation.
  • properties of the sheet such as strength remarkably deteriorate and a suitable sheet formation becomes difficult.
  • the effect of including the leaf tobacco extract within the glucan gel is decreased, and stability of holding the leaf tobacco extract and duration properties of releasing the leaf tobacco extract are remarkably deteriorated.
  • the present inventors have conducted extensive studies to find that the dispersion interference can be prevented if at least one organic acid is added in dispersing powder of glucan into the leaf tobacco extract (or concentrate thereof) as a dispersion medium for glucan, making it possible to produce a heat-irreversibly coagulated glucan sheet holding the leaf tobacco extract at a high content and with good stability and having a satisfactory strength.
  • a second and more preferable procedure for preparing the high viscosity aqueous dispersion containing the leaf tobacco extract and the heat-irreversibly coagulating glucan comprises preparing a mixture containing the aqueous leaf tobacco extract or a concentrate thereof as a dispersion medium, a dispersion interference-preventing agent comprising an organic acid, and powder of the heat-irreversibly coagulating glucan; and stirring the prepared mixture to disperse the glucan powder into the dispersion medium (the leaf tobacco extract or the concentrate thereof), whereby a slurry having an increased viscosity can be obtained.

  • a slurry having an increased viscosity for example, 4,000 - 8,000 mPa ⁇ s at 25°C
  • this slurry preparation is carried out using a mixer and at a temperature of 20 - 30°C as in the first procedure.
  • the concentration of the heat-irreversibly coagulating glucan, in particular curdlan is preferably from 1 to 20% and more preferably from 3 to 5% by weight of the leaf tobacco extract or a concentrate thereof for the same reasons as in the first procedure.

More preferably, glucan is incorporated into the final glucan gel sheet in an amount of 10 to 40% by weight.
  • the oily solvent is incorporated into the final glucan gel sheet in an amount of 30% by weight or less. If the amount is more than 30% by weight, the oily solvent tends not to be included within the resultant glucan gel so that the solvent is liable to be leaked to the outside of the glucan gel.
